From 6bc50a8f69920b2d2b0c5890e2133748b62656c3 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 19 Dec 2018 20:03:13 +0900 Subject: [PATCH] ARM: uniphier: do not modify bootcmd environment variable at run-time Some users might want to modify 'bootcmd' at compile-time by editing include/configs/uniphier.h, but overwriting it at run-time makes it impossible. Instead, set 'bootdev' at run-time, which contains the boot device the system is booting from, then indirectly reference it from 'bootcmd'. It is up to users whether to override 'bootcmd'.
